You can access one of the eight arenas at the time. Each one will display leaderboards. Gold table for gold difficulty (first table) and platinum table for platinum difficulty (second table). You can see teams that competed for the best result, time they have completed arenas, and video recording of the matches (click the time under faction to watch, it will open youtube video). Click The Finals in the center to see which team is the best in the galaxy. Teams are ranked by the amount of completed arenas, and then by speed of their completion.
